I think this might be related to my workstation hardware as the same virtual disk image will boot on a Macbook running the same version of Virtual Box.
The system which fails to boot the disk image is: SXCE Build 117 VirtualBox 3.0.0: 1 Processor, 768 MB RAM, 128MB Video memory, VT-x AMD-V (all settings fail), nested paging (on and off), 20 GB IDE primary master virtual Disk. No serial, floppy, audo, or USB, no shared folders . Physical hardware: ASUS M3A78-T AM2+/AM2 AMD 790GX HDMI ATX AMD Motherboard AMD Phenom II X4 920 2.8GHz Quad Core 8 GB RAM 3 640GB Segate SATA drives, zfs concatenated 2 250 GB Segate SATA zfs mirrored for OS.

This is consistent and so far, only happens with B117. Any ideas? Thanks, John
